Is GBP to blame why Stevenson vs Zepeda can't happen?

[tomhawq]

To put a bit of context into this, a year or so ago Stevenson was calling out these guys, Pitbull, Zepeda, Haney, Loma, etc. Pitbull and Zepeda in particular expressed irritation. Zepeda was mad and asked for an offer. Shakur later tweeted the offer has been sent. Whether true or not, Zepeda went dead silent. Never responded since. Fast forward Zepeda blasted Hughes in his last fight and was calling out Shakur.

And that's where the story ends. There's no continuation. Seems no effort is being made on GBP's part.
